I just picked up a pretty sweet one owner lawnboy 7263 from around 1974, which supposedly runs, however the recoil assembly is malfunctioning. I found a video how to remove one but it looked like a slightly different engine. There is a nut that is supposed to loosen which allows the recoil assembly to slide out, however the bolt is impossible to get to with a wrench. I am only able to turn it less than a quarter of a turn and no more. Do I need to take the carb off so those screws on the carb aren't in the way or should I take the entire flywheel and everything off? Or is there something I am missing? Thanks.
